Before diaphragm ultrasonography, assessment of diaphragm function was very difficult due to the complex nature of its exploration. The use of this new technique has shed light on diagnostic problems and treatment with an improvement in final outcomes for critically ill patients, in whom the incidence of diaphragm weakness or dysfunction has been underestimated. Better knowledge of diaphragm function enables us earlier diagnosis by quantification of diaphragm contractile activity or evaluation of functional status after delivery of plexus block anaesthesia, facilitating therapeutic decisions...

Ultrasound is widely used for medical diagnosis and increasingly for therapeutic purposes. An understanding of the bio-effects of sonography is important for clinicians and scientists working in the field because permanent damage to biological tissues can occur at high levels of exposure. Here the underlying principles of thermal mechanisms and the physical interactions of ultrasound with biological tissues are reviewed. Adverse health effects derived from cellular studies, animal studies and clinical reports are reviewed to provide insight into the in vitro and in vivo bio-effects of ultrasound...

PURPOSE: Trigger finger is a common condition with a lifetime prevalence of 2%. Corticosteroid injection is a treatment often considered as a first-line intervention with reported cure rates between 60% and 90% in observational cohorts. Nevertheless, open surgery remains the most effective treatment with reported cure rates near 100%. Head-to-head trials on these treatments are limited. We investigated the efficacy of open surgery compared with ultrasound-guided corticosteroid injections...

Introduction.:  Tumors invading the sacrum and/or ilium often represent incurable metastatic disease, and treatment is targeted toward palliation of symptoms and control of pain. As systemic opioid therapy is frequently inadequate and limited by side effects, a variety of interventional techniques are available to better optimize analgesia. Using six patients as a paradigm for interventional approaches to pain relief, we present a therapeutic algorithm for treating sacroiliac tumor-related pain in the oncologic population...

OBJECTIVES: Axillary ultrasound with fine needle aspiration (AXUSFNA) in early-stage breast cancer has required reappraisal. ACOSOG Z-0011 and after mapping of the axilla: radiotherapy or surgery have shown that women with limited nodal disease at sentinel lymph node biopsy got no survival advantage with completion axillary node dissection. We hypothesize that AXUSFNA may be sufficiently accurate for staging for some patients and sentinel lymph node biopsy need not be performed. We define the false negative rate (FNR) of AXUSFNA in different subsets of patients...

Therapeutic Ultrasound (US) is a popular modality among healthcare professionals and is used to treat a variety of musculoskeletal conditions.(1) Throughout the past 70 years of clinical use,(2) ultrasound has been shown to be an effective way to decrease pain,(2,3) increase tissue temperature,(4) and decrease tissue stiffness of trigger points,(5) amidst other benefits. Treatment parameters with US are typically high-intensity and occur over a short period of time (minutes). The US machine is large and stationary, forcing patients to be non-mobile for the duration of their treatment...

Ultrasound-enhanced drug delivery through the cornea has considerable therapeutic potential. However, our understanding of how ultrasound enhances drug transport is poor, as is our ability to predict the increased level of transport for given ultrasound parameters. Described here is a computational model for quantifying changes in corneal porosity during ultrasound exposure. The model is calibrated through experiments involving sodium fluorescein transport through rabbit cornea. Validation was performed using nylon filters, for which the properties are known...

Conventional High Intensity Focused Ultrasound (HIFU) is a therapeutic modality which is extracorporeally administered. In applications where a relatively small HIFU lesion is required, an intravascular HIFU probe can be deployed to the ablation site. In this paper, we demonstrate the design and implementation a fully integrated HIFU drive system on a chip to be placed on a 6 Fr catheter probe. An 8-element capacitive micromachined ultrasound transducer (CMUT) ring array of 2 mm diameter has been used as the ultrasound source...

While chemotherapy is a major mode of cancer therapeutics, its efficacy is limited by systemic toxicities and drug resistance. Recent advances in nanomedicine provide the opportunity to reduce systemic toxicities. However, drug resistance remains a major challenge in cancer treatment research. Here we developed a nanomedicine composed of a phase-change nano-droplet (PCND) and an anti-cancer antibody (9E5), proposing the concept of ultrasound cancer therapy with intracellular vaporisation. PCND is a liquid perfluorocarbon nanoparticle with a liquid-gas phase that is transformable upon exposure to ultrasound...

Introduction We studied the extent to which an ultrasound-guided vacuum-assisted biopsy device ("hand-held Mammotome") could be used not only as a valuable tool for investigation of suspicious breast lesions, but also therapeutically for the complete removal of breast fibroadenomas. Materials and Methods 132 aspiration biopsies showing fibroadenoma on histology were collected retrospectively. We ascertained whether there were residual findings on breast ultrasound at a median follow-up of approx. 9 months following biopsy...

Hyeong Seok Nam, Dae Hwan Kang
The therapeutic role of endoscopic ultrasound (EUS) has continued to evolve in recent years. EUS-guided biliary drainage (EUS-BD) can be performed as an effective alternative to percutaneous drainage or surgical options when conventional Endoscopic retrograde cholangiopancreatography fails or is not possible. Depending on the access and exit routes of the stent, multiple approaches to EUS-BD have been proposed. Each patient should receive an individualized approach based on the patient's condition, anatomy, and endoscopist's experience, with an appropriate backup prepared...

OBJECTIVE: Delivery barriers of nanodrug in large tumors due to heterogeneous blood supply, elevated interstitial pressure and long transport distances can degrade the efficacy of cancer treatment. In this study, we proposed a therapeutic strategy to improve the tumor growth inhibition by injecting pegylated liposomal doxorubicin (PLD), and then applying a short time of ultrasound hyperthermia (HT) on the entire solid tumor, and inflicting ultrasound thermal ablation (Ab) in the low-perfused tumor region...

LLL12 exhibits high specificity for inhibiting STAT3 phosphorylation and dimerization, and inducing apoptosis to constitutively activated STAT3 cancer cells without cytotoxicity to normal cells with dormant STAT3. However, clinical deployment of LLL12 in cancer treatment is hindered by its low bioavailability and hypoxia-induced resistance. To overcome these limitations, we encapsulate both oxygen and LLL12 in stimuli responsive microdroplets (SRMs) by a gas-driven coaxial flow focusing (CFF) process for ultrasound mediated treatment of hypoxic cancer cells...

BACKGROUND: Although there are several evidences that suggest efficacies of therapeutic ultrasound (TU) or treadmill exercise (TE) to alleviate nerve injury-associated pain, molecular mechanisms are less clear. We aimed to investigate the impact of TU and/or TE on neuropathic pain induced by chronic constriction injury (CCI) of the sciatic nerve and their roles of proinflammatory and anti-inflammatory cytokines. METHODS: Rats were randomly divided into (n = 10 per group) sham operation (sham), CCI procedure followed by false application of TU (CCI + TU0), CCI procedure followed by false application of TU and TE (CCI + TU0 + TE), CCI, and CCI procedure followed by TU alone (CCI + TU), TE alone (CCI + TE), or both TU and TE (CCI + TU + TE) groups...

Perianal disease, most commonly manifest as fistula or abscess formation, affects up to 40% of patients with Crohn's disease. Perianal Crohn's disease is disabling, associated with poor outcomes, and represents a therapeutic challenge for physicians. Correct diagnosis and classification of perianal disease is the first crucial step for appropriate multidisciplinary management. Areas covered: A literature search was performed of the PubMed database using the terms "transperineal ultrasonography", "transperineal ultrasound", "perianal disease", "perianal fistula", "perianal abscess", "magnetic resonance", "endoanal ultrasonography", "endoscopic ultrasound" in combination with "Crohn's disease"...

INTRODUCTION: Isolated bilateral simplex ectopic ureters (BSEUs) are rare but pose a therapeutic challenge: ureteric reimplantation alone does not accomplish continence in all. Identifying the patients needing additional procedures for continence early could prevent multiple operations. OBJECTIVE: Potential preoperative indicators for postoperative continence are explored in eight BSEU girls without cloacal, anorectal, or spinal anomalies. STUDY DESIGN: With institutional approval, all patients with BSEU between 1985 and 2012 were retrospectively reviewed...
